植物小分子RNA研究进展

植物体内存在多种不同类型的小分子RNA(small RNA,sRNA),在调节植物生长发育、抑制转座子活性和抵御逆境等过程中发挥着重要的作用。近年来,人们在sRNA的产生机制、效应复合物的形成和对靶基因的调控方式及其生物学功能等方面的研究取得了很大进展。该文对这些进展作简要介绍。

Plant small RNAs

Small RNAs （sRNAs） have emerged as key components in the gene regulatory networks of eukaryotes. Several classes of sRNAs have been discovered in plants. These sRNAs play important roles in developmental regulation,inactivation of transposons,and responses to biotic and abiotic stresses. Here,we briefly review the recent progress in understanding the mechanisms of sRNA biogenesis,sorting of sRNAs into effector complexes,modes of sRNA action on their targets and their biological functions.
